Big Cormorant Lake vs Ida Lake
Water quality, depth, fish species, and recreation comparison.
Big Cormorant Lake reads lower on nutrients and algae than Ida Lake. Both are in Becker County, Minnesota.
Both Big Cormorant Lake and Ida Lake sit in Minnesota. A same-state comparison strips out the state-level water-quality regime as a variable: any differences in the readings here are about the lakes themselves, not the agencies sampling them. The readings are close: Big Cormorant Lake and Ida Lake sit within a narrow band of each other on phosphorus, chlorophyll-a and clarity. The per-parameter table below shows where the small differences actually live.
With readings this close, the choice between the two lakes turns on non-water-quality factors: depth, fish species, public access, distance from home. The per-lake pages below cover all of those.
Big Cormorant Lake
Crystal clear, you can see 24.8 ft down.
Ida Lake

Side-by-Side Metrics
| Metric | Big Cormorant Lake | Ida Lake |
|---|---|---|
| Water Clarity | 24.8 ft Better | 12.1 ft |
| Phosphorus | 16.5 µg/L Better | 23 µg/L |
| Chlorophyll-a (Algae) | 2.2 µg/L Better | 5.3 µg/L |
| Maximum Depth | 75 ft Better | 20 ft |
| Surface Area | 3,657 acres | 632 acres |
| Public Access | Yes | Yes |
| Fish Species | 16 Better | 14 |
| Trophic State | oligotrophic | mesotrophic |
A green ✓ marks the better value for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better). Surface area and trophic state carry no tick — a bigger lake is not a better lake.
